My Home made La Scalas

The first time I encountered Klipsch LaScala's was at one of my teammates house. His Sister had a pair of Black formica ones playing Pink Floyd's "Dark side of the Moon" and I couldnt beleive how much better they sounded than the same song on my ipod ha ha ha. I wanted a pair sooo bad. But I faced the classic macroeconomics dilemma of "Music versus Beer".

So I made my own. I visited the local Klipsch dealer and measured one and after a little thought, realized that they had been designed so that you could cut all of the pieces to make a pair from 3 sheets of plywood. To resonate the Bass horn properly with cheaper 15" woofers, I sealed the back of the tweeter/midrange section and cut a hole thru to the Woofer section to increase the cubic feet. They sound surprisingly good for homemade and I use them with my Band a lot on the road as mains. The tricky part is making a jig to cut the angles on the Woofer horn triangle. All I used was a table saw, Jig Saw, drill and a protractor.

Very nice - My brother had a pair of Lascalla when he was in the Air Force and brought them home when he got out - nothing like DSOM cranked on them to ear bursting levels....
 
Hi
Can you email me the plans? I was thinking of building a pair. And do you happen to have Klipschorn plans? All the plans I have are in mm's
Thanks

put @ at the at. :)
 
Roy, Just right mouse click the 2 plans and choose "save picture as". I'll be glad to send them to you as well. Ive seen the Khorn plans around, dunno if in English, I can look and see.
 
PS. Parts express www.partsexpress.com has horns,drivers and speaker building hardware. I used 3 sheets of Birch plywood and a lotta woodscrews and just butt joined the seams as I plan to paint it black anyway. I used a larger tweeter horn that I had, the plans call for a smaller one. use L pads on the mid and tweeter to limit their volume, they easily overpower the acostic suspension Bass horn. The 15" speaker bolts across the slot on part 12. Make 4 part number 2's ,and take 2 each to form an inverted triangle above and an upright one below with their apex at the slot. When the back is on this forms a "horn" channel from the back to the sides to make the folded horn.
 
You might note one big improvement on the new La Scalas was using a full 1" thick side boards for improved bass clairity as the thinner 3/4" had a tendancy to breathe and color the low end! I would use the full 1" sides and back! Thanks for the plans- I am a huge La Scalas fan!

Hi
I did the right click thing and saved them Thanks, I hope you can find the Khorn plans in english the one's I got are in German and mm's. If I go with 1" sides and back the size changes abit, thats not hard to change.
 
Thanks everyone!

The 1" doghouse is a good idea DC, Ive seen people put in side braces in the Bass bin to address that but thicker walls would look better.

I think the total price for this was somewhere around $300.00. The only real expense are the drivers and crossovers. Dont use MDF, use plywood. Birch isnt required if you cover, paint or veneer them. make a rectangle speaker stand out of boards fastended to the bottom to lift the speaker up off of the floor for better response. there is one on mine if you look.

You may want to make a spacer ring to lift the speaker front away from the motor board so the cone dosent buzz against the board at high volumes. I did just to be safe.

Roy, The only ones Ive seen are german, although with a metric to mm converter and redrawing to visualize them better you should be able to "fit' the pieces by going to the larger tolerance and sanding downwards to fit them. I use generous amounts of glue and wood putty to fill in any voids and imperfections ha ha ha.

Nice job, a cheap logic calculator[$11-14 @ any drug store] has a very easy conversion, one button, as does your computor. I've had good success using a PL 400, etc... style construction adhesive. Once built, run a liberal bead down any and all joints, cracks,nooks and crannies. It is a excellent sealer and strengthener.
 
Way cool, we did something similar, a friend made cabinets 30+ years ago and we loaded them with Altec drivers, they sounded great for gigs in a hall; Altec La Scals's

Unless VOT pulls that link, probably so.

Guys, any time you want to post an auction/sale link just for the pictures, simply copy and paste the picture. If you just want to show that some nitwit painted his LaScalas blue, you don't need a Craigslist auction link, you just need the pic.

Plus, (and this is the most important point), if somebody reads this thread next month, the link will be dead and gone, but if you attach a pic, it will live forever!:yes:
 
Yow! I think these people have been watching the Home and Garden Channel too much.

Just bought some tweeters to change out the too big ones I put in my homebrew LaScalas. The seller on a certain online auction place also had LaScala speakerkit midrange horns and drivers for sale if anyone is thinking about building their own set of LaScalas. Bob Cites has everything except the midrange horns available on his site.

Duly noted. I just didn't want to uglify the thread. But to make a point, perhaps it should be documented and archived as you instructed.

Those had to have been in a club or something. They would never "blend in" even if you painted them clear (like with invisiible paint).
